I was wondering whats been the highest amount of players online at the sametime in this game so far?

50 to 150 is what ive seen so far myself, which doesn't seem much IMO.

Here is a link to a thread that contains a link to a graph:

This should give a good estimate. I'm going to have to have it archive monthly graphs soon.
